fix: only import @excel-builder-vanilla/types for optional dep

[ghiscoding]

• since Excel Export is an optional package, we shouldn't install the entire excel-builder-vanilla when the only thing we really use in the common package is the excel-builder-vanilla interfaces for the grid option interface, so we should really only import its types in the @slickgrid-universal/common package and no need to download/install the entire library since we only need its types.
• So to deal with that, I created a new separate types only package. The new package @excel-builder-vanilla/types is only including the d.ts files so that we can use it in the grid options interface without installing the entire lib which is especially true for users who aren't install the Excel Export service @slickgrid-universal/excel-export
